Turbine Wheel
If the turbine wheel is cracked or deformed, replace the turbocharger sub-assembly.

2. INSPECT AXIAL PLAY OF TURBINE SHAFT

Using a dial indicator, insert the needle of the dial indicator into the exhaust side of the turbine shaft.

Move the turbine shaft in the axial direction and measure the axial play of the turbine shaft.
Maximum axial play:
0.11 mm (0.00433 in.)
If the axial play is more than the maximum, replace the turbocharger sub-assembly.

3. INSPECT RADIAL PLAY OF TURBINE SHAFT

Using a dial indicator, insert the needle of the dial indicator into the oil outlet hole, and set it against the center of the turbine shaft.

Move the turbine shaft in the radial direction and measure the radial play of the turbine shaft.
Maximum radial play:
0.112 mm (0.00441 in.)
If the radial play is more than the maximum, replace the turbocharger sub-assembly.

4. CHECK TURBINE SHAFT ROTATION

Rotate the turbine wheel on the exhaust side with your finger and check that it rotates smoothly.
HINT:
Even if it takes effort a little to rotate the turbine wheel, this is not a problem.
If the turbine wheel does not rotate smoothly, replace the turbocharger sub-assembly.
